“…The current waste management system in Malaysia is incapable of digesting the huge disposal rate of municipal solid waste due to the infancy of its incineration process. Thus, the disposal of unwanted waste substances has led to hazardous sustainability issues, including environmental pollution, public and worker health damage, economic growth stagnation, and production competence loss (Chua & Bashir, 2019). Moreover, in the past, the treatment of foreign workers in the industry, non-compliance to social practices, and forced labor have always been topics of controversy raised by stakeholders, implying that manufacturers face difficulties achieving social goals (Kumar, 2019).…”

“…The objective of this paper was to establish SMPs as a dynamic internal strategic action of manufacturing SMEs that transforms firm capabilities into sustainability performance. In summary, environmental and health issues have arisen in Malaysia as a result of the poor implementation of its sustainable management systems and the inability of its current waste management system to handle substantial municipal solid waste disposals (Chua & Bashir, 2019). The Covid-19 outbreak further dampened sustainable development in Malaysia and brought devastating effects to firms' economic, environmental, and social performance.…”

In the Sustainable Development Goals Summit in September 2019, world leaders addressed current and future sustainability challenges faced by the world, including poverty, inequality, climate change, environmental degradation, peace, and justice. However, the Covid-19 pandemic has shocked and dampened global sustainable development efforts. Malaysian manufacturing small and medium enterprises (SMEs) are not exempt from this tragedy, as they have suffered economically, socially, and environmentally. The goal of this paper is to establish sustainable manufacturing practices (SMPs) as a dynamic internal strategic action for manufacturing firms that transforms firm capabilities into sustainability performance. The authors conducted an extensive literature search to explore global sustainability issues and narrowed the scope to issues encountered by Malaysian manufacturing firms. The most commonly used terminologies of sustainability, sustainable practices, and sustainability performance were subsequently analyzed to conceptually develop a holistic framework for future studies. Specifically, the authors proposed an explanatory quantitative study to comprehend the link between firm capabilities and multidimensional sustainability performance with the integration of SMPs as a mediator. The results of the analysis would provide useful recommendations for the manufacturing sector and directions for future studies. Additionally, this paper enriches the theory of the Dynamic Capability View by bringing in the sustainability model to explain the development process of sustainability performance among Malaysian manufacturing SMEs. This article does not just inform firms and authorities on the importance of SMPs for superior performance but also guides firms towards understanding and improving their current SMPs. Managers in the manufacturing sector would benefit from this paper by learning and implementing effective sustainable strategies in their operations management to improve sustainability-related outcomes.

“…For example, the operating temperature is important in plastic pyrolysis as plastics degradation occurs at different temperature depending on the chemical structure of the plastics. Temperature influences the cracking reaction of the polymer chains, thus 19 -Occupation of a large land area 20 -Long decomposition cycle and environment pollution 20 -Restoration of land is not always possible. 21 Incineration -Suitable for commingling with excessive contamination, separation difficulties, or polymer property deterioration 22 Emitting nitrogen oxides (NO x ) and sulfur oxides (SO x ) 23 Pyrolysis -High conversion efficiency and polluting gaseous emissions 23 -Moisture content of feedstock affects yield 19 -Suitable for commingled PW 24 -High cost of operation 19 -A wide range of products, liquid, gas, and solid, can be produced from plastic wastes.…”

Energy Potential of Plastic Waste Valorization: A Short Comparative Assessment of Pyrolysis versus Gasification

Plastics are abundant and have a high energy content making their use in energy applications attractive. This article presents a review on plastic waste (PW) management by pyrolysis and gasification, which are two routes of thermochemical conversion (TCC) techniques. The conversion of PW and the application of its converted products are important steps towards reducing reliance on fossil fuel, enhancing closed-loop recycling of materials and circular economy. The review presented herein also focuses on product distribution and yields with emphasis on the energy content and potential integration to energy systems and grids. It is found that pyro-oils have properties similar to conventional fuels such as diesel and can partially substitute fossil fuels. In fact, the energy content of PW pyro-oils obtained by various researchers range from 41.10 -46.16 MJ kg -1 , which are close to the heating values of conventional fuels, thus are potential candidates for fuel applications. Typical treatment post conversion is also conducted to maintain the quality of the oil produced and the removal of sulphur content to conform with market standards. On the other hand, syngas produced during gasification possesses a lesser potential for fuel applications as its energy content may reach values as low as 20 MJ kg -1 in

“…In 2006-2010, the Master Plan on National Waste Minimization was also introduced. Almost all of these programs were unsuccessful due to ineffective implementation and lack of public participation (Bashir, et al, 2019). The rise in waste generation further exacerbates the situation, as it was projected to reach 36,138 tons per day by 2020; 41,035 tons per day by 2026, and 49,670 tons per day by 2030 (Chua et al, 2019).…”

There Exploring the levels of knowledge, attitude, and practice (KAP) of the citizen is an initial step towards designing comprehensive and participative solid waste management strategies, programs, and policies. A cross-sectional survey was conducted to capture the knowledge, attitude, and practices (KAP) on solid waste management from a total of 107 respondents in Penampang Proper Village, Penampang, Sabah, Malaysia. The study determined the relationship of the independent variables (year of birth, gender, education, and employment) with the dependent variables (KAP) using the Kruskal Wallis correlation test. Relationships were tested at 0.05 levels of significance and Spearman Rho correlation was used to test the relationship between the KAP variables at 0.01 levels of significance. It was found out that most respondents have excellent levels of KAP but none of the independent variables has a significant relationship to the KAP levels. However, the respondents' year of birth and educational level has a significant relationship to their practice level. Spearman Rho test also reveals that knowledge and attitude have a positive correlation with each other. The findings, therefore, may be useful to assist local campaigners in planning message materials, platforms and input to further increase citizen participation.
